4. Symptoms of urinary tract obstruction, such as decreased urine output or difficulty urinating

5. Recurrent urinary tract infections associated with calculi

6. Dysuria, urgency, or frequency in the context of suspected urinary stones

7. History of passing stones or previous diagnosis of urinary calculi

8. Signs of infection (fever, chills) in the presence of urinary stones

9. Physical exam findings consistent with costovertebral angle tenderness
